Need Help Identifying The Sex Of This Guppy

[Veylith]

I started breeding guppies in an 85 gallon tank and my first batch is reaching adulthood but I'm having trouble sexing some of them such as this one because they are colored like males, but have the shape of a female guppy and they're anal fins look elongated but upon closer inspection are not quite like the distinguishable males anal fins. Can someone help me with this? I'm sorry the photos are blurry but its extremely hard to get clear photos of moving guppies.

It might help you if you realise that all guppies start off looking female, and that it takes a while for the gonopodium to develop fully from the female type fan-shaped fin.

I suspect that the fish you're not sure of are males that are just maturing.

Depending on the genetics of the guppies you can easily have colourful females, I know this because almost all of my females are coloured on their bodies, and fins. We are even expanding the tail and fin size in our breeding program to produce females with large paddle shaped tails and long flowing dorsal fins all with colour.
If you look very closely at your young guppies you should be able to see where the future gonopodium of the males is starting to get pointy and elongate while any future females the fin should still look blunt.
These photos might help showing what I mean

All of these are at least a couple of months old.
